Possibly this is of help: Reduce[a^2 > b^2 && a > b] (b <= 0 && a > -b) || (b > 0 && a > b) or Reduce[a^2 > b^2] b \[Element] Reals && (a < -Sqrt[b^2] || a > Sqrt[b^2]) or Reduce[a^2 > b^2, Reals] a < -Sqrt[b^2] || a > Sqrt[b^2] Bobby On Tue, 24 Jun 2008 02:26:32 -0500, pircdefense <gregthaopenny at gvtc.com> wrote: > I'm trying to show for all real numbers whether the following statement > is true or false: > > If a > b, then a^2 > b^2.
